I don't suppose anyone has any tricks to get the AK100 working as a USB DAC on 64bit Windows via a USB 3.0 port?

The official specs state that only USB 2.0 ports are able to be used on a 64 bit OS.... which doesn't help me when I am using a Microsoft Surface Pro which only has a USB 3.0 port.

I've tried connecting it via a USB2 hub connected to the device, but no luck.

It works just fine through my desktop's usb 2.0 port.

If not, I might have to get myself an iBasso D12 or D6. Has anyone compared the USB output of the AK100 to either of those?

Thanks for any help

The Surface pro is USB 2.0 backward compatible, is the pro able to recognize the AK100 as a sound device is another question you should ask. I have a Windows 7 64-bit setup and have no issues recognizing my USB 2.0 compatible dacs which need to be switched from the sound control panel in Windows. As far as the D12, it has an optical in which I believe the AK100 has so you can connect it that way. Just remember I'll will be bypassed and just will work as a transport. You can use the LI but then it's like amping the AK.Edited by musicheaven - 10/2/13 at 2:18am

I have had very good luck with Windows 8 (and 8.1) x64 using USB DACs over USB 3. I have a Fiio E17 and a Schiit Modi and both work better on Windows 8 than on Windows 7. I had noise problems on USB 2 on Win 7. Switching to USB 3 helped but all of the problems went away with Windows 8. I am using stock Microsoft drivers. Don't understand why Schiit and Fiio can make this work, but not iRiver.

Nonetheless, that's not always a bad thing. It makes them great for new age and classical because those genres don't require much upper treble, and it sounds very mellow with rolled off treble. I like it more that way for new age.
